Icosahedral LED display screen

ABSTRACT

An icosahedral LED display screen belongs to the field of display screens and includes multiple cabinet main frames. Each cabinet main frame is formed with an accommodating cavity. A side of each cabinet main frame is provided with a flexible PCB, an outer side of the flexible PCB is disposed with LEDs, and an inner side of the flexible PCB is provided with a magnet fixedly therewith. The multiple e.g., twenty cabinet main frames are mutually connected to form an icosahedral sphere which has no end point similar to a football, and polygons that make up the sphere are the same, and therefore the cabinet main frames can be completely covered by the flexible PCBs to eliminate a missing of display at an endpoint and reduce design numbers and complexities of the cabinet main frames and the flexible PCBs. An installation of the LED display screen becomes more convenient.

FIELD OF THE DISCLOSURE

The disclosure relates to the field of display screens, and more particularly to an icosahedral light emitting diode (LED) display screen.

BACKGROUND OF THE DISCLOSURE

At present, an LED DOME, as a new type of spherical display screen, appears in the market. However, for most of the spherical display screens in the related art, a sphere is divided into two hemispheres, and then each of the two hemispheres is divided longitudinally according to multiple latitudes. The existing spherical display screens mainly have following disadvantages.

Firstly, since there will be an end point of each of the spherical display screens that cannot be completely covered by LED modules, after a spherical cabinet of the spherical display screen is assembled, in a situation that the whole spherical cabinet is used as a display surface, the end point will affect display effect of the spherical display screen.

Secondly, for the hemisphere after the longitudinal division, a single cabinet can be expanded to be a curved triangle, and shapes of the LED modules are different from each other, therefore, the design cost and the difficulty of later installation are greatly increased, and shape design of the spherical cabinet is also complicated.

SUMMARY OF THE DISCLOSURE

The disclosure aims to provide an icosahedral LED display screen, for solving technical problems such as a poor display effect, a complex structure, a high cost and a great difficulty in later installation of lamps in the prior art.

The disclosure provides an icosahedral LED display screen, including multiple cabinet main frames. Each of the multiple cabinet main frames is formed with an accommodating cavity, a side of each of the multiple cabinet main frames is provided with a flexible printed circuit board (PCB), an outer side of the flexible PCB facing away from the cabinet main frame is disposed with LEDs, an inner side of the flexible PCB facing towards the cabinet main frame is provided with a magnet fixedly connected therewith and thereby magnetically connected to the cabinet main frame, and the multiple cabinet main frames are mutually connected, e.g., to form an icosahedron.

In an embodiment, the icosahedral LED display screen further includes a power supply module, and the power supply module is arranged in one of the multiple cabinet main frames.

In an embodiment, the multiple cabinet main frames include at least one type of polygonal cabinet main frames.

In an embodiment, each of the multiple cabinet main frames is a regular triangle in shape.

In an embodiment, an outer sidewall of each of the multiple cabinet main frames is provided with a set of through holes for installing screws.

In an embodiment, the multiple cabinet main frames are twenty in number, and the twenty cabinet main frames are mutually connected to form an icosahedral sphere structure.

In an embodiment, a top end surface of the flexible PCB has the same radian as a top end surface of the cabinet main frame.

Compared with the prior art, the icosahedral LED display screen of the disclosure may have the following beneficial effects.

Firstly, since the twenty cabinet main frames are mutually connected to form a regular icosahedral sphere, there is no end point on the regular icosahedral sphere similar to a football, and moreover polygons forming the regular icosahedral sphere are the same, such that the multiple cabinet main frames can be completely covered by the flexible PCBs, thereby a missing display at an end point in the prior art can be eliminated, design numbers and complexities of the cabinet main frames and the flexible PCBs are reduced, and an installation of the cabinet main frames becomes more convenient.

Secondly, an outer sidewall of each cabinet main frame is provided with a set of through holes for installing screws, and each flexible PCB is magnetically connected to a corresponding cabinet main frame, which can realize the whole quick disassembly and assembly of the multiple cabinet main frames and improve the whole practical performance thereof.
